STRAP TYPE WRIST SUPPORT This is a continuation-in-part of my prior application Ser. No. 767.969 filed Oct. 16, 1968, now abandoned.

This invention relates to wrist supports. particularly those of the type used by bowlers, golfers, or by people engaged in any physical activity wherein some wrist support action is desired.

Heretofore there have been various types of wrist supports manufactured and sold in some quantities, and one type of a wrist support is shown in US. Pat. No. 3,238,939. Such wrist support comprises generally V- or L-shaped member with a thumb engaging aperture provided at the connection between the legs of the L-shaped wrist support. It has been somewhat difficult to wrap the short leg of this wrist support around one's wrist and then to affix the support in position by winding the long strap leg around the wearers wrist to be attached thereto. Other wrist supports are shown in US. Pat. Nos. 2,369,115 and 2,369,2l0.

The general object of the present invention is to provide a novel and improved wrist support member which can be readi- 7 ly and easily applied by any person to his wrist for wrist support or bracing action.

Another object of the invention is to provide a relatively trim appearing, low cost wrist support that can be easily and snugly affixed to a wearer's wrist, and which wrist support has fastening members provided on opposite faces thereof at longitudinally spaced portions of the wrist strap to attachthe strap in an operative position.

Another object of the invention is to provide a special reinforcing pocket and a reinforcing member in a wrist support to brace the wrist at the wristjoint to more-or-less lock the wrist in a fixed position.

In the drawings:

FIG. 1 is a top plan of the brace of the invention;

FIG. 2 is a bottom plan of the wrist brace;

FIG. 3 is an enlarged section through the attachment means of the wrist brace;

FIG. 4 is an enlarged section through the pocket in the wrist brace;

FIG. 5 is a perspective view of the wrist brace operatively positioned on a person 5 Wrist; and

FIG. 6 is a top plan of a wrist brace or support, with the pocket of the wrist brace shortened to a rectangular shape.

In general, the wrist brace 1, according to the invention comprises a semi-flexible, compact, and comfortable unit that easily allows itself to be wrapped around an outer extremity of the body, especially the wrist. The brace preferably has a finished plastic layer or surface 2 and a fabric inner surface or layer 3. As the brace is positioned around the wrist, the thumb goes through a thumb hole 6 and the fastening means 4, 5 are connected. The fastening means are provided on opposite faces at opposing longitudinal ends of the brace 1. Furthermore, said fastening means comprise a pile member 4, of relatively fine fibers positioned on the inner surface near the wider end of the brace at the thumb hole, and parallel to the longitudinal axis of the brace, the pile means being of general rectangular shape. The other fastening means, the hook member 5, usually a Velcro tape of spaced vertically positioned hook elements, is positioned on the finished surface 2 of the brace at the end remote from the thumb hole, and said hook member being elongate and parallel to the pile member. The hook member 5 is rectangular but usually shorter than the pile member. The use'of this Velcro fastening means gives convenience to the user of this invention. It permits him ease of attaching and ease of removing the brace, with a wide range of length or wrist size for adjustment of the brace so as to adapt to the wearer. The fastening members are joined together by any force or pressure exerted thereon, so that the brace acts as a one-piece unit wrapped around the wrist.

The wrist brace l primarily is made from a strap or strip of material that may be laminated, as shown, or not and which is made from a suitable plastic or fabric material. The strap of material preferably has no, or a very limited longitudinal stretch. The strap is of generally wedge shape or it may be considered to be of frusto-triangular shape. It may be considered to have a very short section-I0 extending rearwardly from the hole 6 and an appreciably longer section 11 of decreasing width extending from the thumb hole at about 90 from the other section. The strap has slight resiliency or elasticity in its depth direction i.e. perpendicular to the line 4-4 of FIG. I.

For the left hand strap, as shown in FIG. 6. the brace I would just be turned over with relation to the right hand strap as shown in FIG. I.

unit which is furthest from the thumb hole. Inside this pocket is the primary bracing element of the invention comprising a thin metal strip or sheet 8. similar to a slat of a conventional venetian blind, with a lateral curvature so when the brace is positioned on the wrist. the metal strip 8 follows the curve of the back of the wrist. This strip 8 is considered to extend trans versely of the brace. The metal brace provides more comfort for the wearer than if the metal brace were fiat in nature and not conforming in general to the curvature of the hand and wrist. This metal brace is slidably engaged in the previously mentioned pocket and. if for some reason the metal brace is desired to be removed, the owner of the brace can easily remove it from. the pocketv This sheet or brace 8 of thin similar shape and of different or semirigidconstruction, or, more than one bracing member may be positioned within the open-ended pocket, thus obtaining a more rigid unit than that consisting of one bracing member. The front edge of the metal sheet or strip 8 likewise has in inclined front edge for at least a portion of its length to abut on the edge 9. The strip or brace 8 may be of any suitable width and length to fit in the pocket and usually extends substantially the width and length thereof to fit readily in the pocket and form a reinforcement on an axis extending along the back of the hand and over the wrist towards a wearer's forearm.

A variation of the type of wrist brace and reinforcing pocket previously discussed is shown in FIG. 6. By employing additional stitching 15a and 15b an enclosed rectangular pocket 7a is formed, with brace 8a also enclosed therein, leaving vacant tion for use, normally, by golfers to prevent excessive wrist break on the back swing. Thus the drawings show a left hand wrist support, FIG. 6 from the inside, and a right hand wrist support, FIG. 2 from the inside. Either support may be used for wrist reinforcement by athletes but the supports are particularly designed for use by golfers and bowlers in the designs as shown.

The pocket in the wrist brace la may be made from a plastic covered slightly resilient fabric like that used in forming the remainder of the brace. More wrist mobility is permitted fora golfer in the wrist support 1a than in the unit of FIG. 1. However, the wrist supports 1 and la both firmly support and reinforce the wearers wrist when snuggly attached thereto. The braces or metal plates 8 and 8a prevent backward bending of the wrist with a tighter reinforcement being provided by the support I. In its shown form, the support is made from a lamination formed of the fabric layer 3, plastic layer 2, and a resilient intermediate foam layer 12. The plastic layer 2 may be made from a vinyl resin material or the like and the foam layer may be polyurethane, foam rubber or the like. These layers can be desired limited stretch depthwise or transversely of the strap.

Conventionally attached to the inside of the brace I is a curved metal sheet, may be replaced by one or more items of pocket 7 follows the front edge 9 of the wrist brace and the secured together by conventional adhesives and/or by heat The attaching means strip may be parallel to the strip 4 or the strip 5 may be substantially parallel to the front edge 9. By inclining the strip 5 at an angle of about to l5 to the longitudinal axis of the strip 4, as indicated in FIG. 1, the strip 5 is in better register with the strip 4 when the wrist support is operatively positioned.

Naturally the positions of the hook strip 5 and the pile strip 4, and the lengths thereof, can be reversed from the structure shown so that a short hook strip may be on the section 10 and an elongate pile strip may be on the longer section 11. As the hook strip is more expensive than the pile strip, the foregoing construction may be preferred.

The wrist support is compact and easily attached. By its general wedge shape, it reinforces the back of the wrist and adjacent areas. However, it does not extend over any large area of the palm but nicely engages and extends around the wrist and an adjacent short length of the wearer's forearm. The novel shape of the support and its compact size and effective bracing action give the wrist support desirable properties. Flexibility is provided by the areas 13 and 14 to prevent any cutting action by the brace 80 which itself is light in weight and flexible but reenforced by its confining fabric pocket.

While what has been described is considered to be the most advantageous embodiment of the invention, it is apparent that many modifications and variations can be made in the specific details, construction and arrangement of parts without departing from the spirit and scope of the present invention, as those skilled in the art will readily understand. Such modifications and variations are considered to be within the purview and scope of the invention.
